docker搭建pxc

1、下载镜像

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io   加速器(https://www.daocloud.io/mirror)

systemctl restart docker

docker pull percona/percona-xtradb-cluster

2、tag镜像

docker tag percona/percona-xtradb-cluster pxc

docker rmi percona/percona-xtradb-cluster

3、创建volume

docker volume create --name v1
docker volume create --name v2
docker volume create --name v3
docker volume create --name v4
docker volume create --name v5

4、创建桥接网络

docker network create pxc_network --subnet 172.19.0.0/16

5、依次启动容器

docker run -d -p : -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -v v1:/var/lib/mysql --privileged --name=node1 --net=pxc_network --ip 172.19.0.2 pxc
docker run -d -p : -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v2:/var/lib/mysql --privileged --name=node2 --net=pxc_network --ip 172.19.0.3 pxc
docker run -d -p : -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v3:/var/lib/mysql --privileged --name=node3 --net=pxc_network --ip 172.19.0.4 pxc
docker run -d -p : -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v4:/var/lib/mysql --privileged --name=node4 --net=pxc_network --ip 172.19.0.5 pxc
docker run -d -p : -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v5:/var/lib/mysql --privileged --name=node5 --net=pxc_network --ip 172.19.0.6 pxc

6、连接测试

使用navicat连接mysql进行测试

haproxy

docker pull haproxy

vim /usr/local/etc/haproxy/haproxy.cfg

global
    chroot /usr/local/etc/haproxy
    log 127.0.0.1 local5 info
    daemon

defaults
    log    global
    mode http
    option    httplog
    option    dontlognull
    timeout connect
    timeout client
    timeout server  

listen  admin_stats
    bind  0.0.0.0:
    mode http
    stats uri  /dbs
    stats realm  Global\ statistics
    stats auth  admin:abc123456
listen  proxy-mysql
    bind  0.0.0.0:
    mode  tcp
    balance  roundrobin
    option  tcplog
    option  mysql-check user haproxy
    server  MySQL_1 172.19.0.2: check weight  maxconn
    server  MySQL_2 172.19.0.3: check weight  maxconn
    server  MySQL_3 172.19.0.4: check weight  maxconn
    server  MySQL_4 172.19.0.5: check weight  maxconn
    server  MySQL_5 172.19.0.6: check weight  maxconn
    option  tcpka

docker run -it -d -p 4001:8888 -p 4002:3306 -v /usr/local/etc/haproxy/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg --name h1 --privileged --net=pxc_network --ip 172.19.0.7 haproxy
